Function preserves_schema::syntax::block::escape_bytes

pub fn escape_bytes(bs: &[u8]) -> String

Escapes bs into a Rust byte string literal, treating each byte as its ASCII equivalent except producing \\ for 0x5c, \" for 0x22, and \x.. for bytes outside the range 0x20..0x7e, inclusive.

This process is intended to generate literals compatible with rustc; see the language reference on “Byte string literals”.
